The JB4 is the most advanced and highly featured tuning system available for your B38, B46, and B48 powered BMW. Power gains are up to 40hp to the wheels (55hp crank) for a B48, gains with bolt-on parts, higher octane, E85 mixtures, and larger turbos are even higher. The JB4 features a simple plug & play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in-dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features. Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization, but for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or JB4 mobile phone adapter. The JB4 automatically detects between the B38, B46, B48 models at boot up making installation and setup a snap. Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. A separate JB4 Mobile app purchase is also required. JB4 Map Guide: Map0: Stock tuning, fully disable JB4 Map1: 3psi over stock added (91 octane) Map2: 4psi over stock added (91-93 octane) Map3: 6psi over stock added (93+ octane) Map4: Absolute target map with peak target of 20psi (93+ and/or 30% E85, EWG connector suggested) Map5: Absolute target map with peak target of 22psi (30% E85+ fuel, EWG connector suggested) Map6: Custom tuning map -- see details on JB4tech.com B58 JB4 page Map7: Progressive WMI map with tuning a function of meth flow and user-defined boost additive.

The MOTIV ReFlex+ is an Advanced I/O Integration module allowing a level of precise control of auxiliary components. In addition, the ReFlex can incorporate external data into the factory DME/ECU in parallel through optional CANbus integration. Utilizing the CANbus option, multiple digital and analog signals can be used by the DME/ECU for safety, data logging, or adaptive tuning features. It is unique in its ability to function as a separate standalone, as well as a parallel module in conjunction with the DME/ECU. The ReFlex provides the most accurate and precise supplementary sequential fuel injection with the ability to control other advanced features all in one place. It brings a new level of control, function, and versatility to tuning any modern-day vehicle. Preset crank and cam trigger for most modern-day BMW engines, as well as fully configurable triggers to be synched on any vehicle application. Configurable to operate on 4, 5, 6, and 8-cylinder engines. 3 Point MAP sensor calibration table makes it configurable for almost any MAP or TMAP sensor. Sequential Port Injection with the ability to sense individual injector failures on 4 to 8-cylinder engines. Built-in Ethanol Content Analyzer. The Re|Flex firmware and XDFs include ethanol compensation tables to scale properly for varying ethanol % based on real-time input from the sensor. 2x Additional Outputs. These outputs have 12x12 resolution tables for control in TunerPro R/T. These can be configured to run as on/off, digital, frequency (25hz), or PID. Boost Control WGDC Methanol Solenoid Control PWM (for use with valves such as the Aquamist FAV and the ProMeth Pulse Valve) Nitrous Solenoid Control PWM Auxiliary fuel pump relay trigger 2x Inputs Ethanol Content Sensor Fuel Pressure Sensor (0-10bar) Oil Pressure (0-10bar) Coolant Pressure (0-10bar) EGBP/EMAP (0-10bar) CANbus (not required) enabled communication for the transmission and receiving of digital signals for fully DME/ECU integrated control of external modifications. The CANbus communications also allow for data and errors to be transmitted to and from the vehicle's engine control computer in order to add safeguards and implement engine trips and fail safes. Logging via OBDII is still fully functional and is not affected at all by the communication with the Re|Flex. Some of the developments underway include: Error reporting to and from factory ECU for unparalleled safety Output WGDC by converting an EWG signal to a more conventional DC output for controlling standard 3port and 4port boost solenoids for use with external WG’s The ability to datalog non-factory parameters such as ethanol content, additional pressure sensor, PI IDC, and more! These features make the Re|Flex the most powerful and safest supplementary and auxiliary controller on the market. However, this is only the beginning. As flash platforms find the need for more accessories to control, the Re|Flex was designed to be updated easily by the end user in order to add functionality as it is developed.

Their innovative throttle tuning system lets you tune your engine’s reactions to your taste – choose from 7 separate stages (Eco+, Eco, Neutral, Sport, Sport+, Race, and Race+). Your engine’s performance isn’t affected by RaceChip XLR, but you can access it more immediately and directly. Experience significantly sharper responses for yourself – no waiting for the message to get through or frustrating “pauses for thought”. And the best thing: installation is simple and requires no specialist knowledge. Try it now! The Brainbox: The Brainbox is the nerve center of XLR and controls the processes needed to optimize throttle response. The Brainbox’s compact size (ca. 70 x 80 mm) allows it to be fitted easily in the footwell of your vehicle. As it is so flat, it does not restrict the driver’s legroom at all. It can be fixed almost anywhere in the footwell, for example in existing slots or vents. The Controller: The XLR Controller allows you to choose between 7 stages: Eco+, Eco, Neutral, Sport, Sport+, Race and Race+. Each stage sharpens your car’s throttle response a little more, until in Race+ it’s like a thoroughbred sports car. You can mount the Controller anywhere in the car so that it’s in the right place for how you want to use it. The size and design mean it fits right in with the rest of the interior and the other control elements.
